Description of the preferred Embodiment ,.
Referring specifically to FIG. l, a pagin~ system is illustrated which embodieq the present invention. The paging system includes a telephone lO which is utilized by a calling party to initiate a page. Telephone lO is coupled to a computer terminal ll by means of a standard telephone line. Computer `~ terminal ll i8 controlled by a paging system operator who composes messages on the computer terminal in response to messages from the calling party on telephone lO. Computer terminal ll is coupled through a paging ter~inal 12 to a central transmitter 13 and an acknowledge receiver 14. It will of ~' course be understood by those skilled in the art that transmitter 13 and receiver 14 may be in a single unit utilizin8 ~ 20 a single antenna or they may actually be positioned remotely from each other. For example, in any specific area it may be advantagous to interconnect a plurality of spaced apart receivers in a network around the area to reduce the amount of 1 3 ~ 3 ~ ~ ~
l power required for a pager to reach any speciric receiver. The @
~` system further inc1udes at 1east one remotely located pager 15.
Referring specificnlly to FIG. 2, the remote pager 15 is illustrated in si~plif'ied block form. The pager 15 inc1udes an ~, 5 antenna 16 coupled through a tran~mit/receive ~witch 17 to c. either a transmitter 18 or a receiver 19. Antenna 16, switch ~: 17, transmitter 18, and receiver 19 operate in the normal well ~; known fa~hion and will not be elaborated upon further.
q The output of receiver 19 is coupled to an address signal decoder 20 and to a data decoder 21. The output of data decoder 21 is coupled to a data display ancl control logic circuit 22, ,~
~,i; which in turn control~ an LCD display 23. A plurality of ,. ;~
display control inputs 24 through 27 are coupled to the data ~, display and control logic circuit 22 from external controls which will be described presently. Address signal decoder 20 ~:' provides enable signQls to data decoder 21, data display and control logic circuit 22, and an acknowledge signal encoder 28.
The output of acknowledge signal encoder 28 is coupled to a r',~ modulation input of transmitter 18. Acknowledge signal encoder .~ 20 28 also has a plurality of inputs 29 through 32 from a plurality i~ of message selector controls which will be described presently.
'~ Referring specifically to FIG. 3, a plan view of the display 23 and controls of pager 15 is illustrated. A plurality ~i of switches A, B, C, and D are illustrated as the message ~; 25 selector controls for inputs 29 through 32, respectively, of :"
~ acknowledge signal encoder 28. The switches A through D may be ::
; simple push button switches, toggle switches or any other type . ,. ~
;; 4 ~' :
;,;
':, . .
:: ~31.3~
of switch which may be utilized for the purposes to be deYcribed presently. Four display function controls, READ, MEMO~Y, VOLUME, and DISPLAY, are included on the con-trol panel on pager 15 and are connected to inputs 24 through 27, respectively, of data display and control logic circuit 22. Data display and control logic circuit 22 contains a memory and the circuitry required to store and format a message for proper display by LCD
display 23. The READ function control provides a signal on input 24 which cnuse~ control logic circuit 22 to bring a 10 message from the memory and supply :it to LCD display 23. The function control labelled MEMORY provides a signal on input 25 to cause con-trol logic circuit 22 to store the next message received from data decoder 21 in the memory. The function control labelled VOLUME provides a signal on input 26 to logic circuit 22 which changes the volume, in a prescribed direction, of any acoustic signaling device that may be coupled to logic circuit 22 in addition to LCD display 23. Finally, the function control labelled DISPLAY supplies signals to logic circuit 22 O11 input 27 to cause logic circuit 22 to change the brightness of diSplay 23.
Each of the message selector switches A, B, C, and D, supply signals to acknowledge Qignal encoder 28 which cause encoder 28 to supply a different code to transmitter 18 for modulating the RF signal produced thereby. It will of course be understood by those skilled in the art that there are a great variety of codes which may be utili2ed by acknowledge si~nal encoder 28, including a simple digital code, frequency or ~ 3 ~
amplitude modulation, or any of A variety of other well known schemes. It will also be understood that the messa8e selector switches A, B, C, and D, can simply be push button switches which automatically cause an encoded transmission upon depression thereof or they could be a type of toggle switch which simply controls acknowledge encoder 28 and transmission occurs in response to a transmission switch (not shown) which is operated after the ~essage selector controls are properly positioned. In this preferred embodiment the message selector switches A, B, C, and D, are simple push button switches which automatically cause a transmis~ion upon the depression thereof, which transmission is encoded with a simple digital code.
In the operation of the paging system, a calling party contacts the paging system operator at computer terminal ll by means of telephone 10. He requests a page of a specific pager, for example pager 15, and further requests the paging system operator compose a message asking the owner of pager 15 what time he would like to mee-t Mr. Jones for dinner. In addition to the primary message (the question), the calling party provides the paging sy~tem operator with a number of alternate responses, or times, he will be available for dinner; 6pm, 7pm, or 8pm.
The ~alling party further instructs the paging system operator that in the event none of these times are available to the pager user being contacted that he should call back the calling party. The pa~ing ~ystem operator composes a message on computer terminal ll which includes the primary message and the alternate responses as shown on LCD display 23 of FIG. 3. The .
~L3~3~
messa~e i~ transmitted by way o~ pAgin~ terminal 12 snd transmitter 13 to psger 15.
The me~age, which al~o cont~in~ ~ psger addr~
received by r~cei~er 19 and supplied to addre~s sign~l decoder 20 and dsta dec~der 21. Addres~ ~ignal decoder 20 decode~ the ~ddress portion of the message and, if the address i~ the same a8 pager 15, supplies ~n ackn~wled~e enable ~ignal to ackno~ledge signal encoder 28, an en~ble ~ignsl to dat~ display ~nd control lo~ic 22 and an en~ble si~nAl to data deooder 21.
When data decoder 21 receive~ the enable signal from ~ddress cign~l decoder 20 the mes~sge from receiver 1g i8 decoded and the dat~ upplied to logic oircuit 22. Sinoe lo~ic circuit 22 h~s also received an enable ~ignal, the decoded mesQage activat~s an acoustic signal or oth~r alert device in pa8er 15 snd is supplied to the memory ~orming a portion of data ~i~play and control logic ~. When the pager user he~r~ the acou~tic signal and oper~tes the READ oontrol the ~e~ge ~ppear~ at LCD
display 23 of pager 15 ~ illustr~ted in FIC. 3.
Upon reading the message on the pager LCD display 23, the pager user determines a response to the question and select a message selector switch A, B, C, or D which corresponds with the answer he desires to transmit i.e. switches A, B, C, and D
are correlated with the displayed responses 6 PM, 7 PM, 8 PM, and call back, respectively. The pager user than depresses the message selector switch which automatically transmits an encoded message from transmitter 18 to ackn~wledge receiver 14 to both acknowledge receipt o~ the paging signal and indicate the user designated response to the question thereof. The received response is conducted through paging terminal 12 to computer terminal 11. Computer terminal 11 mat¢hes the received encoded ~;ignal with the corresponding alternate response, i.e.
~3~99 6pm, 7pm, 8pm, or call back, and provides the alternate response to the paging system oper~tor by meQnQ of a di~play or the like. The pa~ing syste~ oper~tor then provides the calling party with the ~elected alternnte response. It sho~ld be under~tood that the message from the pager might be interpreted by the computer terminal and an approl)riate recorded vo~ ce respon~e ~or other response i~nal) r~ yed to the calling party without intervention by the psging system oper~tor. Thus, the pa~er has provided an acknowledge si~nal a8 well a~ at least a partial response to the que~tion of the cslling party.
While no specific message coding format has been de~cribed herein it will be under~tood by those ~killed in the Art that a variety of mes~age format~ may be utilized. A t~pical me3~age format which might be utilized in the present psging ~ystem is described in the book entitled "A Standard Code for ~adiopaging"
published in July of 1979 wherein the international nsme for POCSA& is "CCI~ Rsdiopa~ine Code No. 1 (Rec 584, Geneva, 1982, POCSAG-Code); U.S. Patent No. 4,518,g61, entitled "Universal Paging Device with Po~er Conservation", is~ued May 21, 1985; and a copending PCT patent application entitled "System for Off-The-Air Reprogrammine of Communication Receivers", bearing erial number PCT/US87~00004, filed January 2, 1987.
The pre~ent invention optimize~ the information that can be conveyed with a limited set of acknowledge signals by assigning a variable 8et of meaning-Q to each acknowledge ~i~nal. ThiC functiDnnl assignment is accomplished by ~3138~
transmitting the meaninB of each of the return 8ignal~ as part of the initial paging ~ignal. Since the centr~l transmitter is not handicapped by limited power and/or time, the transmission of the additional portion of the me~sage is not B problem.
While the pager illustrated utilizes an LCD displ~y, it will be understood by those ~killed in the art that other types of indicators might be utilized, such ~ imple voice ~peaker, slthough this would not be as desira~ble a~ the described display becsuse of the pO8~ ibility of errors ~nd the like.
